NumPy may fail to build with the default vendored distutils in setuptools>=60. Rather than panic and die when new setuptools is found, let's check (or set, if possible) the SETUPTOOLS_USE_DISTUTILS environment variable that restores "proper" setuptools behavior.

Backport of #20963.

We were bitten by #20759 and #20795 in Void Linux, which has already moved to setuptools>60.
Note that I cannot reproduce a build failure (at least not on maintenance/v.1.22.x) even when the new default isn't overridden. (That is, reverting https://github.com/numpy/numpy/pull/20759/https://github.com/numpy/numpy/pull/20795[](https://github.com/ahesford) is sufficient to allow NumPy to build for me.) However, in certain cases where it the new default might cause problems, this change should thread the needle. Sticking with setuptools < 60 for the next year while NumPy moves to a new build system is simply not a good option for Linux packagers.
